Economics Module 10: Circular Flow and GDP

Study Notes

The Simple Circular Flow Diagram

Household: Represents individuals or groups sharing income, they consume goods and services.
Firms: Organizations or businesses that produce goods and services for sale and employ household members.
Product Markets: Where households purchase desired products from firms, driven by consumer spending.
Factor Market: A marketplace where firms acquire factors of production, primarily labor, from households.

The Expanded Circular Flow Diagram

Government Spending: Total purchases by federal, state, and local governments, impacting overall economic activity.
Taxes: Compulsory payments from households and firms to the government, influencing disposable income and economic health.
Tax Revenue: Funds collected from taxes are used for government expenditures and services.
Disposable Income: Income available for consumption after taxes are deducted, calculated as income - taxes.
Transfer Payments: Government payments to individuals, adding funds to the household sector, enhancing consumption capacity.

Financial Markets in The Circular Flow Model

Private Savings: Funds not spent by households, creating leakage from the circular flow, which can influence investment.
Government and Investment Spending: Essential for economic growth, influencing overall circulation of money.
Inventories: Reflects investment spending in holding goods for future sales, impacting firm production decisions.

Adding the Rest of The World to the Model

Export Payments: International sales inject cash into the U.S. circular flow, benefiting domestic firms.
Import Purchases: Outflows of funds when households and firms buy foreign goods and services, representing a leakage.
Net Exports: Calculated as exports minus imports, indicating the trade balance and its effect on GDP.

Gross Domestic Product (GDP)

Definition: Total market value of all final goods and services produced in the economy within a specified time frame, usually annually.
Final Goods and Services: Products sold directly to consumers that are not required for further production.
Intermediate Goods: Inputs used in the production of final goods and services, not counted in GDP to avoid double counting.
